just played the game again so i could complete it and no more crashes!! tho i think a sticking point for me is how i'd rather just avoid the birds instead of taking them down. this is partly because on keyboard moving from spacebar to J doesn't feel very smooth and i'm more inclined to keep moving instead of lifting my hand from the jump key unless necessary for progression. but also they're pretty easy to avoid, you can just run past or over them, even the red ones just jump over you lol, if they knock out one of my monkeys i can get them back easy. so maybe a banana reward (since they are supposedly stealing the bananas) from taking them down, or other incentive would be good there.
